Short answer

How do I fix malformed JSON from my AI?

Your agent uses the parser to strip trailing commas and fix single quotes. You get a strict, valid JSON object that works in any standard environment. Here is how it handles the data.

The results.

Where every error lands.

The parser cleans up the syntax so your downstream tools don't crash.

CLEAN

Valid JSON output

The parser removes trailing commas and extra punctuation. You get a clean object that follows strict standards.

FIXED

Standardized quotes

Single quotes and unquoted keys get converted to double quotes. This makes the data predictable for your code.

READY

Immediate use

The output is ready to be piped into a database or script. You won't need to write custom regex to clean it.

REVIEW

Human oversight

The agent identifies what it changed. You decide if the repaired structure matches your original intent.

The workflow

What your AI does when malformed data arrives.

When an agent hits a syntax error, it hands the text to the parser to rebuild it.

  1. Detect errors

    The agent identifies where the JSON structure breaks, like missing quotes or extra commas.

    parse_json5

  2. Repair syntax

    The parser interprets the non-standard text and maps it to a valid format.

    parse_json5

  3. Standardize quotes

    The tool converts single quotes to double quotes to meet strict requirements.

    parse_json5

  4. Return object

    The agent receives the corrected JSON object to continue the task.

FAQ

How this task behaves.

  • 01

    Can the AI fix my logic errors?

    No. The parser only fixes syntax errors like commas and quotes. It does not change the actual data or the meaning of your keys.

  • 02

    Will it delete my data?

    No. The tool only reads the text you provide and returns a corrected version. It has no permission to delete files or modify your original source.

  • 03

    Does it work with any JSON-like text?

    Yes, it is designed to handle non-standard formats that regular parsers reject.

  • 04

    Can I use this in Cursor or VS Code?

    Yes, any MCP-compatible client can use this once connected.

  • 05

    Does the AI decide how to fix the data?

    The parser follows strict rules to make the syntax valid. You are responsible for verifying that the resulting structure is what you expected.
